Bacon, Onion and Mushroom Quiche

I love quiche and yet I rarely make it which is odd because it's so easy.  This is one of my favorite quiche combinations.

1 pie crust (homemade or store bought)
1 cup sliced mushrooms
1/3 cup diced onion
4 pieces of bacon (cooked and crumbled)
1 cup shredded cheddar
5 eggs
1 cup heavy cream
salt and pepper to taste

Heat oven to 350. Prepare the curst in a pie plate.  In a bowl combine the mushrooms, onions, bacon and cheddar. Season with salt and pepper.  Pour the ingredients into the pie crust.  In a medium size bowl whisk together the eggs and heavy cream.  Pour the mixture over the bacon and mushroom mixture.  Bake for 45 minutes or until the quiche is set and cooked through.
